ATWD 2420 - Tool & Die Welding

Credit Hours: 3.00

Objectives:

1. Identify tool steels.
2. Weld several examples of fabrication or repair of tools or dies along with the welding procedure used.

Outcome 2: Upon completion of this course, students will be able to identify heat treatment, tempering, and chemical analysis with emphasis on filler metal selection.

Objectives:

1. Demonstrate the chemical analysis, heat treatment and tempering of these steels.
2. Select the process and filler metal to weld the tool steels.
3. Prepare the welding procedure for the weld considering joint design, pre-heat, post-heat, peening, and cleaning.
